Gravitational theory

拟议的研究计划的目标是获得引力理论和量子引力及其对整个宇宙，黑洞和宇宙内其他结构的影响的重要新知识。 在宇宙学中，我的主要目标是在解决测量问题方面取得进展，这个问题是如何预测宇宙中观测的概率，这些宇宙膨胀得如此之大，以至于几乎所有可能的观测都几乎肯定会发生在某个地方。 我已经证明了这个问题在逻辑上与标准量子理论的规则无关，因此需要新的规则。 我还发现，许多试图解决测量问题的方法都预测了一个荒谬的结果，即我们很可能是玻尔兹曼大脑，是由热或真空波动而不是生物进化和自然选择形成的高度无序的观察者。 我计划研究解决测量问题和避免玻尔兹曼大脑灾难的想法，例如不给更大空间更高概率的测量，这将优先考虑未来玻尔兹曼大脑占主导地位的时代。

The objectives of the proposed research program are to gain significant new knowledge of gravitational theory and quantum gravity and their implications for the universe as a whole, for black holes, and for other structures within the universe. In cosmology, my main goal is to make progress toward solving the measure problem, the problem of how to make predictions for the probabilities of observations in universes that have inflated so large that nearly all possible observations are almost certain to occur somewhere. I have shown that this problem is logically independent of the rules of standard quantum theory, so new rules are needed. I have also found that many attempted solutions to the measure problem predict the absurd result that we are most likely Boltzmann brains, highly disordered observers that would form by thermal or vacuum fluctuations rather than by biological evolution and natural selection. I plan to investigate ideas I have for solving the measure problem and for avoiding the Boltzmann brain catastrophe, such as measures that do not give higher probabilities to larger volumes of space that would give preference to future epochs when Boltzmann brains would dominate.
